A long solenoid with 10.0 turns/cm and a radius of 7.00 cm carries a current of 20.0 mA
Chapter 29, Problem 55(choose chapter or problem)
A long solenoid with 10.0 turns/cm and a radius of 7.00 cm carries a current of 20.0 mA. A current of 6.00 A exists in a straight conductor located along the central axis of the solenoid. (a) At what radial distance from the axis will the direction of the resulting magnetic field be at 45.0 to the axial direction? (b) What is the magnitude of the magnetic field there?
